cara 2 :
6/4 + 32/6 = 36/24 + 128/24 = 164/24 = 6 20/24 = 6 5/6
no. 2
5 4/3 ÷ 4/5 = 19/3 ÷ 4/5 = 19/3 ×5/4 = 80/12 = 6 8/12 = 6 2/3
no. 3
6/7 × 22/15 ÷ 2/3 = 27/7 × 22/15 × 3/2 = 297/35 = 8 17/35
no. 4
5.000 × 43 = 215.000
no. 5
20/33 × 150 = 9,99............/10 ⇒ dibulatkan
no. 6
25% ÷ 60% × 20% = 25/100 ÷ 60/100 × 20/100 = 1/4 ÷ 3/5 × 1/5
= 1/4 × 5/3 × 1/5 = 1/12 = 8,33...........%/ 8% ⇒ dibulatkan
no. 7
6 7/4 ÷ 4 = 31 × 1/4 = 31/8 = 3 7/8
